Izitena zeNtsimbi ezigelezayo
Izitena zentsimbi ezigelezayobhekisa kwizitena ezingenanto ezirhabaxa ezibekwe kwimiqolomba yepleyiti esezantsi ye-ingot casting ukuze kuqhagamshelwe izitena zentsimbi ezihambayo kunye ne-ingot mold, eyaziwa ngokuba yi-runner brick. Isetyenziswa kakhulu ukunciphisa ukumelana nokuhamba kwentsimbi enyibilikisiweyo kunye nokuthintela ukuvuza kwentsimbi. Iimpawu eziphambili ziquka ukumelana noxinzelelo lobushushu obuphezulu, ukumelana nokuguguleka, ukunyibilika kakuhle, ukufakwa lula kunye nokumelana nomlilo okuhle.
1. Uhlu ngokwezinto eziphathekayo:
Udongwe: (1)Olu lolona hlobo lulula lwezitena zentsimbi ezisetyenziswa ngodongwe oluqhelekileyo. Nangona ixabiso liphantsi, alunakumelana nomlilo kwaye alusebenzi kakuhle, kwaye lufanelekile kwezinye iifektri ezincinci zentsimbi okanye kwiimeko zokusetyenziswa okwethutyana.
(2) I-aluminium ephezulu:Esi sitena sentsimbi esihambayo sinomxholo ophezulu we-aluminium, sinokumelana okuhle komlilo, kwaye sinokuhlala sizinzile kwiindawo ezinobushushu obuphezulu. Sisetyenziswa rhoqo kumashishini amakhulu entsimbi, ingakumbi kwiinkqubo zokwenza intsimbi ezifuna ukumelana nobushushu obuphezulu ixesha elide.
(3)Iintlobo ngeentlobo:Iikristale ezimile okwenaliti zinolwakhiwo olunqamlezileyo lwenethiwekhi, olunokuthintela ngempumelelo ukukhukuliseka yintsimbi enyibilikisiweyo. Okwangoku sesona sixhobo siphambili.
2. Uhlu ngokwemisebenzi:
(1) Izitena ezisembindini
Isetyenziswa kwindawo engundoqo yokuhamba kwentsimbi enyibilikisiweyo, ixhasa indlela yokuhamba kwaye ifuna ubuninzi
ukunganyangeki kunye nokumelana nokukhukuliseka.
(2) Izitena zokwahlulahlula zentsimbi
Isetyenziselwa ukujika intsimbi enyibilikisiweyo iye kwiimold ezahlukeneyo. Iinkcukacha eziqhelekileyo ziquka imingxunya ephindwe kabini, ephindwe kathathu, nephindwe kane, kuxhomekeke kwiimfuno zenkqubo.
(3) Izitena zomsila
Zifumaneka ekupheleni kwenkqubo yokuhamba kwentsimbi, ziyamelana nefuthe lentsimbi enyibilikisiweyo kunye namaqondo obushushu aphezulu kwaye zifuna ukumelana nokuqhekeka.
1. Ukumelana okuphezulu kobushushu obuphezulu
Ziyakwazi ukunyamezela ubushushu obugqithisileyo be-1500–1700℃ yentsimbi enyibilikisiweyo ixesha elide. Izitena ezisebenzisa i-mullite, umzekelo, zinokumelana okungaphezulu kwe-1780℃, nto leyo eyenza ukuba zilungele iimeko zokusetyenziswa kwe-casting ezishushu kakhulu.
2. Ukumelana nokukhukuliseka okunamandla
Ngesakhiwo esixineneyo nesinamandla aphezulu, ukuphoswa kwezitena kunokumelana ngempumelelo nokukhuhla okubangelwa kukuhamba kwesinyithi esinyibilikisiweyo ngesantya esiphezulu, okunciphisa ukuguguleka nokukrazuka ngexesha lokusebenza.
3. Ukumelana nokugqwala okugqwesileyo
Ziyakwazi ukumelana nokukhukuliseka kweekhemikhali okuvela kwintsimbi enyibilikisiweyo kunye neenkunkuma ezahlukeneyo. Iifomyula zezinto ezahlukeneyo zilungelelaniswe neemeko ezithile zokusebenza.
4. Ukumelana okuhle nokutshiswa kobushushu
Ziyakwazi ukunyamezela ukuguquguquka kobushushu ngokukhawuleza ngexesha lenkqubo yokubumba ngaphandle kokuqhekeka okanye ukuqhekeka.
5. Ungcoliseko oluphantsi kwintsimbi enyibilikisiweyo
Ulwakhiwo lwezinto ezixineneyo lunciphisa ukuxobuka kunye nokuchitheka kwamasuntswana, luthintela ukungena kokungcola kwintsimbi enyibilikisiweyo kwaye luqinisekisa ubunyulu kunye nomgangatho weemveliso zentsimbi yokugqibela.
6. Ukuchaneka okuchanekileyo kobukhulu
Zinemijelo yangaphakathi egudileyo, iimilo zangaphandle eziqhelekileyo, kunye nokumelana okuqinileyo. Oku kuqinisekisa ukuba amalungu angenamthungo ngexesha lokufakelwa, kunciphisa ukumelana nokuhamba kwentsimbi enyibilikisiweyo, kwaye kuthintela iingozi zokuvuza kwentsimbi.
